Excel last year’s date – There are several ways to find the same date in the previous or next year based on a given date. This time, we will use the Excel EDATE function to convert today’s date to a date from last year with a matching weekday.
Convert a Specified Date to Last Year’s Date in Excel
We will use the following three functions to convert today’s date or a specified date to the date with the same weekday from last year.
Excel EDATE Function
The EDATE function is one of the date functions available in Microsoft Excel. It is used to calculate a date a specified number of months before or after a particular date. This function is especially useful for tasks such as financial analysis and project management.
The basic syntax of the EDATE function is as follows.
= EDATE(start_date, months)
start_date: The date from which to begin the calculation. It must be in a date format recognized by Excel.
months: The number of months to add to or subtract from start_date.
A positive value calculates a date after start_date, while a negative value calculates a date before start_date.
Using the Excel EDATE Function
We will use the EDATE function to convert dates entered with a formula that automatically enters dates by weekday into dates from last year with the same weekday.
Dates for each weekday have been entered automatically in the DATES column.
In column 4, we used the EDATE function to convert the dates to dates from last year with the same weekday, as shown below.
The formula used is as follows.
C4 cell =EDATE(TODAY(),-12)-(WEEKDAY(EDATE(TODAY(),-12),3))
Using -12, we first converted today’s date to last year’s date. Then, using the WEEKDAY function, we calculated the Monday of the week containing that date from last year.
